When is it usually safe to start sleeping flat on the back after breast augmentation?

I allow my patients to sleep in any desired position that is comfortable to them, after breast augmentation surgery, from the night of surgery on. I believe you and the implants are not that fragile. You won’t pop or displace their implants by sleeping on them; implants are extremely durable. It's always best, though, to check with your surgeon about his or her protocol. For more information on this and similar topics, I recommend a plastic surgery Q&A book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths." Good luck.

Now. There is no problem sleeping on your back, or sides after breast augmentation . Regards, Dr Steve Merten, Sydney

Thank you for the question.
I would suggest that you run this question by your plastic surgeon given that he/she is ultimately responsible for your care and knows  your situation and the operation performed intimately.
In my practice, most patients are able to sleep on their back within a week and on the sides roughly 2-3 weeks after surgery (with pillow for support as well as supportive bra on).
Best wishes.
